The same thing is done by placing stale bread soaked in vinegar on the baking paper . In this case you will have to preheat the oven to 180 degrees for 15 minutes before placing the bowl with the bread and wine inside, but this time leaving the oven off for one night. The next morning just open the oven, remove the bowl and leave the door open for at least an hour.

If you don’t have bread, prepare a solution with white wine vinegar (or lemon juice) and water. Pour it into a spray bottle and spray on the inside walls of the oven, including the glass and grill. Leave on for two hours and then rinse everything off with a sponge.

Finally, you can also prepare a paste based on water and bicarbonate of soda to use it on the walls of the oven, leaving it to act for 5-10 minutes and then rinsing everything well. Baking soda also eliminates bad odors.
